Notes
It’s hardly a secret that the NVIDIA cards perform exceptionally well in Doom 3. There’s no exception here, as the 6600 GT enables very playable frame rates at 1024x768 and 1600x1200 alike. In SLI mode, the story is even better, dampened only by the 6800 GT’s strong performance than suggests a single-card solution would be better than two 6600’s. ATI is hardly competitive at all here, barely doing at 1024x768 what BFG’s 6600 GT OC does at 1600x1200.
